It’s your startup, so you can give early partners any title you want, but be aware of potential investor and peer implications. VCs and Angel investors like to see a startup that is running lean and mean, with no more than three or four of the conventional C-level or VP titles.

Some would say that if you have a title at all, you are not doing enough work.
